I added this to a post on the Ice Fishing General Discussion Forum back in December. This seems like a good time to bring it forward and add it to the Catfishing Forum. Most of us are going nuts waiting for some open water cat fishing so make a few of these to help pass the time and you will add one more tool to your cat tackle box.
I call these In-Line Scent Bottles for lack of a better name. I made a few of these last summer and field tested them with varying degrees of luck. All I did was take a pill bottle and drilled it full of holes, don’t forget to drill holes around the lid and the bottom of the bottle too. I double thread my cat leader through a bead about 4″ above the hook (this is to keep the bottle from sliding down to the hook). I then thread the leader through the bottom, up through the bottle and out the lid. Then put some stink bait in the bottle with a big hunk of cut bait on the hook in front of the bottle. I used the Berkley Blood scent Bait chunks, I would chop them up into small pieces and keep them in a small coffee can with a small plastic spoon. It is easy to fill the bottle, snap on the lid and ready to go. The filled bottle would last about 15 to 20 minutes which was about the time I normally change cut bait too. It seemed like the warmer the water, the faster the scent bait dissolved. I caught channels on this rig pretty regular but I was also catching them on rods rigged with straight cut bait so I’m not sure if it helped or not. It sure did not seem to hurt anyway.
